How to Test Tire Pressure Gauge

How to Test Tire Pressure Gauge

For the tire to have a good overall performance, you should maintain the proper tire inflation. It contributes a lot to how the car can be maneuvered on the go.

Your car can give you a more comfortable ride as well as better fuel efficiency. Tires that are properly inflated have a longer life span, and they respond quickly to steering.

You should get the right inflation as over inflation and underinflation will both give your troubles. Tire failure and premature tread wear can happen. 

You have to check the tire pressure every month. You can use the tire pressure gauge tester. 

It’s easy to use the mentioned equipment, and you can do it yourself with the guide below. You can check the pressure of the tire and refill it.

Kinds of Tire Pressure Gauge

Different tire pressure gauges types are available in big-box retailers, auto part stores, and online. The usual pressure in them is 60 psi. 

But the range of pressure is between 5 to 99 psi.

1. Dial Gauge

This gauge looks like a clock face with a simple needle to point out the pressure for you to know. There are numerous features aside from being a pocket-sized object.

It has a bleeder valve, dual scale dial, extension hose, and dial cover that is shock resistant. This kind of gauge is readable.

Some models with an extension hose require two hands when being operated. They’re bulky and can cost more than the others.

2. Digital Gauge

It’s easier to read as it resembles a pocket-size calculator with an electronic LCD. It is also dust and dirt resistant. 

Some of them light up so you can check the pressure in low-light or dark areas. This gauge is bulkier and needs batteries to function. Though the batteries can run for years or shorter, you still need to get the replacement.

3. Stick-type Gauge

It’s simple and compact, as it looks like a ballpoint pen. This gauge is affordable. 

With all of the convenience, it’s a little bit harder to interpret compared to the other kinds of the gauge.

Things to Do When Testing Tire Pressure Gauge

1. Starting with Cold Tires

It is recommended to start with cold tires if it’s possible as manufacturers specify PSI or ‘pounds per square inch’. PSI is the unit used in checking the tire pressure in gauges.

They may have the assumption that tires are cold. Cold tires occur when the car remains immobilized for three hours or more. 

The vehicle can have cold tires too when it is driven for less than a mile or 1.6 km at a moderate speed.

2. It’s Important to Check Manufacturer’s PSI

You should not get the correct PSI by a mere guess or eyeball method. It’s necessary to check the cold tire PSI allotted for front and rear tires.

If ever you can’t find the information that you need, you have to contact the manufacturer, your vehicle dealer, and tire professional. 

3. Take Note of the PSI

You have to take note of the PSI for each tire so you won’t be confused. 

4. How to Check the Tire Pressure Using a Gauge

The valve cap should be removed from the tires. Hiss sound should be eliminated while you gain readings from your gauge. 

Put the pressure gauge on the valve stem, and you have to use force when pressing it down. Measurement units are shown in bars, and it will appear on the screen if you use a digital gauge. 

You can check the pressure four times and write all your readings down.

5. Filling Based on the Recommended PSI

You need an air compressor for tires with low pressure. Be attentive with the directions as compressors are different.

When you’re using a compressor at a gas station, place your vehicle in an area where all of the tires are accessible. Insert coins into the machine when you hear the motor working.

Place the end of the hose on the valve stem to fill the tires with air. You need to press the lever to complete this step.

Doing this may make your tires hot. So when it happens, you have to apply 4 psi. 

When tires get cold, you have to check the air pressure again. It’s necessary to always use your gauge as you’ll be able to release some air if it’s overinflated.

Never use your car when tires are overinflated as it causes decreased impact absorption, decreased traction, and premature wear. 

6. Monthly Testing

You have to use your tire pressure gauge every month. You have to do it to ensure that your tires don’t go below optimal PSI. 

Accuracy of Tire Pressure Gauge

The main thing you have to consider when getting a tire pressure gauge is the accuracy. You don’t have to spend much money. 

If you’re not sure about what to get, you can ask for advice from a professional technician. You should get your own rather than borrowing the one at the service station as the latter can be worn out, so accuracy is not reliable.

Summary: Importance of Checking Tire Pressure with a Gauge

Even though you rarely drive or mount your vehicle, tires can’t break away from losing pressure over time. Undamaged tires that are properly mounted on the rim lose pressure from the rubber sidewall.

When the weather gets colder, tire pressure decreases. A tire has 30 psi during 80-degree temperature, but your gauge will show it as 25 psi when the temperature drops by 30.

It’s better to keep your gauge at room temperature to avoid inaccuracy. The tire’s air pressure is not affected by the car’s weight.

Use the pressure setting given by the manufacturer when you check and add air to your tires. You may find it on a sticker or placard located inside the fuel filler door or glove compartment. It can also be on the doorjamb or user’s manual.
